我国东南丘陵区化肥和农药污染状况分析

Analyses on the Status Quo of Chemical Fertilizer and Pesticide Non Point Pollution in Hilly Red Soil Region of Southeast China.

过分省和典型地区化肥和农药使用情况对比，结合实地调查采样分析的研究方法，从不同尺度上分析了我国东南丘陵区化肥、农药扩散污染的状况及其发展趋势。结果表明，浙江、广东和福建３省化肥和农药施用量较高，引起的扩散污染也较为严重；广西、湖南、海南和江西４省化肥和农药的施用量还不高，但近期有迅猛上升的势头。

By making the comparisons of chemical fertilizer and pesticide application rates in different provinces and typical regions, and by adopting field investigation and sample testing study approach, the status quo and the trend of chemical fertilizer and pesticide non point pollution in hilly red soil region of Southeast China have been analyzed in various aspects. The results of the study showed that this kind of pollution in Zhejiang, Guangdong and Fujian provinces was more serious than in other provinces owing to relatively higher application rates of chemical fertilizers and pesticides. The application rates are increasing dramatically in Guangxi Zhuang Autonomous Region and in Hunan, Hainan and Jiangxi Provinces, though the rates are not high presently.
